g v MM HUGH r. ELLARD, or MISSOULA, MONTANA.

CABLE-GRIP.

Application filed July 8, 1915.

To all whom it may concern:

Be it known that I, HUGH F. ELLARD, of Missoula, in the county ofMissoula and State of Montana, have invented certain new and usefulImprovements in Cable-Grips; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

The object of my invention is to produce a simple and highly eificientcable or rope grip for use in moving loads such as logs, etc, from placeto place by a transmission rope or cable.

In the accompanying drawing, Figure 1 is a side elevation the full linesshowing the position of the parts when closed, the dotted linesindicating their open position. Fig. 2 is a detail view of one of thegripping jaws. Fig. 3 is a detail of the link. Figs. 1 and 5 show aslight modification of the jaws.

Referring to the drawing, 1 designates the bar constituting the mainframe of the device, and adapted to be made fast as at 2 to a load,while the jaws 3 at its other end are for attachment to the moving ropeor cable by which the load is to be transported.

One of the essential features of my invention is to provide means foropening and closing the jaws which will insure the maxi- Q mum grlpplngactlon upon the cable, and at the same time permit 'of varying the gripaccording to the size of the cable. I also arrange the parts so thatwhen locked they do not project outward unnecessarily, and hence areunlikely to catch in tree branches or other obstructions. I have shownthe bar 1 formed near its forward end with a pair of laterallyprojecting ears or lugs 4, and a gripping jaw 5. The bar has a secondpair of cars or lugs 6 shown at about its central portion, and belowthese the bar is channeled as at 7 to constitute a receptacle for themain operating lever when the device is locked.

The jaw S is carried on a lever 9 fulcrumed on the lugs 4 and the mainoperating lever 10 is fulcrumed 0n the lugs 6. Levers 9 and 10 areconnected by the link 12. This link is of peculiar formation. Itcomprises a sleeve Specification of Letters Patent. Patented Feb. 2?191'7.

13 shown fulcrumed on the lever 9 and intercrumed on the short arm ofthe lever 10 and is received by the sleeve. This bar has spaced apartlateral portions to receive the short arm of the lever 10 and throughthese lateral portions extends a bolt 15 having a cotter-pin 16. By thismeans the bar may be removed from the lever and turned to project itinward -or outward relatively to the sleeve to enable the jaws toaccommodate rarious sized cables and to vary the tension of the aws onthe cable as the weight of the load may require. I

In order to insure the jaws meeting squarely, that is, to avoid anylateral play between them I have shown the meeting face of one of thejaws provided with alinement pins 17 to be received by correspondingrecesses 18 in the meeting face of the opposite aw.

'It is sometimes desirable, in order to avoid pinching or biting thecable when the relative position of the load and the rope is variable,to have the jaws disposed at varying angles to the position of thegripping device.

To meet this requirement the'jaws may be pivotally mounted on theirrespective bar and lever, as shown in Figs. 4: and 5, where bolts 19allow the machine proper to swing relatively to the jaws.

I claim as my invention:

1. In a cable grip, a bar having a jaw, a levercarrying a j aw andfulcrumed on said bar, a second lever fulcrumed on said bar, and meansfor adjustably connecting said levers.

2. In a cable grip, a bar having a jaw, a lever carrying a jaw andfulcrumed on said bar,a second lever'fulcrumed on said bar, a.

link connecting said levers, and means for adjusting said linktoregulate the movement 7 of the jaw carrying lever.

3. In a cable grip, a bar lever carrying a jaw and fulcrumed on. saidbar, a second lever fulcrumed on said bar, a link connecting saidlevers, and means for adjusting said link to regulate the movement ofthe jaw carrying lever, said link comprising a threaded sleeve fulcrumedto one of having a jaw, a
